Features

Shannon SSD OCS Venice Series

Shannon Open Channel SSDs are the commercialized OCS implementation in industry with volume deployment in hyperscale data centers.

  • Key-Value Store

    The performance of traditional KV store highly depends on the amount of host memory utilized. Shannon’s KV-Store, based on Open Channel SSD directly stores key value pair on flash, while only leaving indexes in the host memory. With the same amount of host DRAM, Shannon’s KV-Store can accommodate more data than traditional KV store in memory, offering performance improvements up to orders of magnitude.

  • Atomic Write

    In order to ensure the data integrity under extreme circumstances, MySQL/MariaDB/Percona/InnoDB enable DoubleWrite by default. As a result, one piece of user data are written twice to the flash. Shannon’s Atomic Write in Open-Channel SSD implements the atomicity of DB page-write without modifications to the applications or file systems. By utilizing Shannon’s Atomic Write with DoubleWrite turned off, application’s access latency can be reduced by up to 50%, while increasing life expectancy of the SSDs.

  • Namespace

    Within virtualized IT infrastruture, traditional methods for resource management such as Cgroup are used. However, these solutions are not always effective. Shannon's Open Channel SSDs allow user to create multiple namespaces to handle data from different application. Each namespace can be configured independently on features such as capacity, performance limits and IO priority, efficiently implementing IO prioritization,scheduling and isolation.
